22 Claims.

This invention relates to improvements in extension supports forcabinets for ironing machines of the domestic type, and moreparticularly to an outboard support which may be folded out of the wayinto the cabinet when the ironing machine is not in use.

One object of the invention is to provide in combination with a cabinetand an ironing machine of the domestic type adapted to be stored withinsaid cabinet and. arranged so as to be withdrawn from the cabinet foruse and supported by the latter in horizontally extended operatingposition outside of the cabinet, means which may be extended from thecabinet tosupport the same in upright position against the overbalancingaction of the projected ironer machine, thereby dispensing with theusual outboard leg on the ironer machine proper employed for supportingand bracing the structure against tilting.

Another object of the invention is to provide in a cabinet ironercomprising a cabinet and an ironer mechanism adapted to be folded intothe cabinet when not in use and to be moved out of the cabinet toextended horizontal operating position and supported from the cabinet,auxiliary supporting and bracing means for said cabinet to preventtilting of the same due to overbalancing tendency of the extendedironer, wherein said auxiliary supporting means is arranged to be foldedinto the cabinet when not in use and to be swung outwardly to operativesupporting position to brace the cabinet while the ironer is inoperating position.

A further object of the invention is to provide in a structure of thecharacter described in the preceding paragraph a safety device in theform of latch means for locking the ironer unit against withdrawal fromthe cabinet in the event 40 that the extension support is not in properposition to brace and support said cabinet against tilting.

Other objects of the invention will more clearly appear from thedescription and claims herein- 45 after following.

In the drawings, forming a part of this specilication, Fig. 1 is avertical, sectionalview'through a cabinet and associated ironermechanism, corresponding substantially to the line' I-I of Fig. 4,

50 illustrating my improvements in connection therewith, said viewshowing the extensible supporting means in operative position and theironer unit in extended horizontal operating position.

Fig. l-a is a top plan view, on a reduced (Cl. S12-28) scale, of thecabinet ironer shown in Fig. 1 with the extensible support in operativeposition, the ironer mechanism being omitted in said view.

Fig. 2 is a view similar to Fig. 1 but illustrating the parts indiiferent positions, the ironer mecha- 5` nism and extensible supportbeing shown as folded within the cabinet.

Fig. 3 is a view on an enlarged scale, similar to Fig. 1, showing onlythe mechanism at the bottom portion of Fig. `1 and showing in addition,10 in dotted lines, the relative positions of certain parts of thestructure when the ironer mechanism is latched against removal due tothe extensible support not being positioned properly to brace andsupport the cabinet.

And Fig. 4 is a horizontal, sectional View, on an enlarged scale andpartly broken away, corresponding substantially to the line fi--d ofFig. 1.

In said drawings, A indicates a cabinet designed to house and support anironer mechanism, and the same may be of any suitable type for thepurpose. The cabinet is preferably made of sheet metal in the shape of arectangular, boxlike structure and sufliciently high to enclose thereinthe ironer mechanism in an upright or vertical position. The cabinet Ahas a door opening I Il closed by a single door II hinged at one edgeand adapted to swing outwardly. The cabinet is preferably provided withcasters I2-I 2 so that it may be moved about as desired.

The ironer mechanism, which is indicated by B, is of the domestic typeand is a unit by itself in the sense that its parts are all related insuch a manner that it can be bodily swung out from the cabinet intooperating position or swung back into the cabinet to enclosed positionwhen not inY use.

The unit employed in the construction shown consists of an elongatedbaseboard I3, which is flat and of substantially rectangular outline andprovided with the usual hinged extension leaf, not shown. Adjacent toone end, this baseboard supports a head or standard Ill, on which anironer roll I5 and its cooperating shoe I 6 are mounted. The roll andshoe extend parallel to the baseboard I3 and are actuated throughsuitable, well known, drive mechanism contained Within the standardV I4.Suspended from beneath the baseboard I3 at the end thereof adjacent tothe standard I4 and fixed to said board is a suitable driving motor I1and a housing |I8, which contains the driving connections between v themotor and the standard I4.

The cabinet A carries supporting means, on which the ironer unit ismounted and by which it is supported and guided in its movements intoand out of the cabinet and supported outside of the cabinet in operatingposition. At its extreme inner end, the baseboard I3 of the ironer unitB has upstanding arms or hangers IS-IB, one on each side of the board,which carry flanged rollers 15J-i9 arranged to ride in guide channels orrails Ztl-20. One of these guide rails is mounted on each side wall ofthe cabinet A, oeing secured thereto in any suitable manner. As clearlyshown in Figs. 1 and 2, the lower forward end portions of these guidechannels are horizontal and the rearward portions thereof extend in acurve rearwardly and upwardly so that the ironer unit will beV bodilyrotated into vertical position when moved into the vcabinet and into ahorizontal position when withdrawn from the cabinet. A adjacent to theforward ends of the guide rails 2li- 20 are two vertical guide channelsor rails 2i-2l, one oneach side of the cabinet. Links 22-22 at oppositesides of the ironer unit B have their outer ends pivotally connected todepending bearing brackets 23--23 on the baseboard I3 of said unit andhave their inner ends provided with rollers 2li- 24 guided by the rails.2t-2t. The links 22-22 are further connected to the cabinet A by a pairofV links 25-25. Each link 25 is pivotally connected at one end to thelink 22 at the corresponding side ofthe Vironer unit B. The other end ofthis link is pivoted to a fixed supporting member 26 on the rail 2i atthe corresponding side of the cabinet.

The mechanism thus far described is well known and is related to thepresent invention only in so far as it cooperates with the parts of thesame, and therefore needs no further detailed' description.

In withdrawing the ironer unit B from the cabinet A and placing the samein horizontal operating position, the attendant grasps the lower endportion of said unit and pulls the same outwardly. During outwardmovement of the unit, the same is swung from the position shown in Fig.2 to that shown in Fig. 1 through the action of the links 22 and 25 andthe cooperating guide means on the ironer unit B and the cabinet A,comprising the rails 20 and 2l, the roll I9 on the ironer unit, and theroll 24 on the link 22. To return the ironer unit to enclosed positionwithin' the cabinet, inward 'and downward pressure is applied to theouter end of the unit, thereby moving the same from the position shownin Fig. 1 to that shown in Fig. 2. As will be evident upon reference toFig. 2, as the withdrawing movement ofv the ironer Yunit is started theoutward swinging movement of said unit about its upper end will causethe pivotal 'connection between the links 22 and 25 to traveltoward andapproach the vertical guide rail 2l. The lower end ofthe link 22, thatis, the end carrying the roller 24, as seen in Fig. 2, will thus beforced to move downwardly along the rail 2l until the pivot between saidlinks passes beyond said rail, whereupon the roller end of the link 22will move in an upward direction along said rail 2 I. Said upwardmovement of the end of the link 22 continues during the further outwardmovement of the ironer unit B until the link reaches the position shownin Fig: l.

As will be evident, outward movement of the ironer unit B will bepositively prevented by holding the roller ends of the links 22-22against said downwardk movement along the rails 2 I-2'I In connectionwith myi improved construction,

At the front of the cabinet I provide a locking means for this purpose,which precludes withdrawal of the ironer unit B in the event that theextensible support is not properly positioned to brace. and support thecabinet with the ironer unit outside of the cabinet in horizontaloperating position.

The extensible support is preferably in the form of a bail member 21swingingly carried by the cabinet for movement into and out of the sameand to extended substantially horizontal position. The bail member 21 isof generally U- shaped outline comprising a pair of spaced, parallelside armsY 28-28 connected at their outer ends by a curved transversesection 29 and having their inner ends laterally outwardly offset, asindicated at 3-3. The bail member 27 is supported interiorly of thecabinet at the bottomfthereof by pivot members 3i-3l carried bysupporting brackets 32-32 at opposite sides of the cabinet and fixed tothebottom wall thereof. The supporting brackets 32--32 are in the formof elongated members having upstanding ears 33-33 adjacent to the rearor inner ends in which'the pivot members or pins 3l--3I are fixed. Theside arms 28--28 of the bail member 2l are spaced apart sufficiently toclear the ironer unit when the bail member is swung upwardly to thesubstantially vertical position shown inFig. 2 and has its movementinwardly of the cabinet limited by a stop 34 at the top of the cabinetadjacent to the front thereof. Tension springs 35-35 are provided, whichyieldingly oppose downward swinging movement of the bail .member 21 and'assist in raising the same to its enclosed position within the cabinet.One of such springs is preferably provided on each side of the cabinet.Each spring 35 has one end thereof secured to the corresponding side arm28 of the bail member 21 forwardly of the pivot 3| and has the other endthereof xedly anchored to the supporting bracket for the rail 2D at thecorersponding side of the cabinet, as indicated at 36, said anchoragebeing adjacent to the back of the cabinet. The bail member 2T has fixed,laterally outwardly projecting stop pins 31-37 at opposite sidesthereof, which also serve to connect the springs 35-35 to the bailmember. The pin 31 on each side of the bail member-2l is rigid with andprojects from Vthe corresponding side arm 28 thereof and is spaced ashort distance forwardly of the pivot of said arm and overhangs andcooperates with a swinging latch or locking plate 38 mounted on thecorresponding bracket 32. As will be understood; two such latch platesare provided, one on each side of the cabinet, cooperating with thepins. S'i--S'l of the arms 28--28 of the bail member 2?. The outer orfront end portion of the bail member 2l is offset with respect to theinner portion thereof, thereby disposing said front portion at a lowerlevel than the inner portion when the bail member is swung to itshorizontal position, as clearly shown in Fig. l. The extreme outerend'portion of said bail member 21 is disposed at an angle to theadjacent portion thereof to provide a foot 39 adapted to rest squarelyon the floor on which the cabinet is supported.

At the forward end thereof, each bearing bracket 32 is provided with anupstanding post 40, byV which the swinging locking plate 38 issupported, a pivot pin 4! extending through the top portionV of saidpost and the plate 38 being provided for this purpose. The post 40 alsohas a pair of spaced stop fingers 42 and 43 thereon,

which cooperate with a laterally projecting stop pin ifi on the plate38. A tension spring d5 secured to the lower portion of the plate 33, asindicated at 56, and to an upstanding lug `lll on the inner end portionof the bracket 32 eX- erts a yielding pull on said plate 38 to rock thesame on its pivot in a clockwise direction, as viewed in Figs. l, 2, and3.

Each latch plate $8 is provided withan arm l on the inner side thereof,which has its outer extremity in the path of movement of the lower endor the link 22 at the corresponding side of the cabinet. As shown inFig. ll, eacharm d8 is in the form of a bent bar of substantiallyZ-shaped form having the inner end or foot portion thereof ilatlyengaging the corresponding side face of the plate 38 and securedthereto, and having the outer end portion thereof olset laterally from`the latch plate, disposed parallel to said plate, and extending in ancpposite direction to the inner `end or foot portion of said bar anddisposed in a plane between the corresponding link 22 and its `roller2li so as to be engaged by the bearing trunnion o said roller.

The arms i3-9.8 of the two latch plates lit-3S are in operativeengagement with the lower ends of the links 22-22 when the ironer unitis folded within the cabinet A, as shown in Figs. 2 and 3, movement ofthe ironer unit into the cabinet being instrumental in swinging thelatch plates 38-38 against the resistance of the springs :t5-i5 to soposition the arms dS-id To eiect this swinging movement of the latchplates -BL actuating means, which is engaged by the outer end portion oithe baseboard i3 of the ironer unit B on movement into the cabinet oithe ironer unit, is provided. This mechanism comprises a pair of rockersfigliti located at opposite sides or the cabinet and rods or links.5B-5t operatively connecting the rockers to the latch plates 323-33.Each rocker i9 comprises a cylindrical shaftlike portion 5l having crankarms 5?; and 53 at opposite ends thereof. The shaft portion 5l of eachrocker is rotatably mounted in a suitable supporting bracket li xed toand uplstanding from the bottom of the cabinet A.

The bearing bracket Eilis in the form of a at bar secured to the bottomwall oi the cabinet having vupstanding end portions with bearingopenings in which the shaft portion 5i is rotatable. The crank arm 53,which is at the outer end of the shaft portion 5l, has its outer endbent at right angles to provide a laterally eX- tending crank pin, whichis rotatably connected to the rear end of the link or rod 5l) at thecorresponding side of the cabinet.y The front end of the link 5G ispivoted or swiveled to the top portion of the corresponding latch plate38 by a pin 55. The crank arm 52, which is at the inner end of the shaftEl of the rocker lli), has the outer end thereof bent laterallyinwardly, as indicated at l56. The arms 52--2 of the rockers (t9-i9 arelonger than the arms 53-53 and are disposed in the path or swingingmovement of the baseboard i3 of theironer unit B. As shown most clearlyin Figs. l, 2, and 3, the crank arm 52 of each rocker is angularlyoffset forwardly of the arm 53 thereof.

As will be evident, when the ironer unit B is swung into the ,cabinet A,the outer or lower end of the baseboard I3 will engage the arms 52-52of. the rockers 49-49 and swing said arms rearwardly, thereby rockingthe arms 53-53 in the same direction and through the links 5KB- 59 rockthe latch plates 33-38 so as to swing the arms dilt8 thereon upwardly tothe position shown kin Figs. 2 and 3,' said upward swinging movementbeing limited by the stop pins til- M of the latch plates 38-33 engagingthe stop fingers ft2-l2 oi the posts ber 2l during swinging movement ofthe bail.

member downwardly toward and upwardly away from the bottom of thecabinet when the plate 3i! is in the position shown in Fig. 2, that is,when the ironer unit is in its completely enclosed vertical position inthe cabinet. The outwardly curved edge 55 of each plate 3B is ofgradually decreasing radius from the outer'to the innerA end'thereof andserves to hold the bail member 2l in lowered position when the plate 38is swung into position to engage ever the pin 3l of the bail member 2l,as shown in Figs. l and 3 (said position being the full line position ofthe plate in Fig. 3).

When the bail member 2l is in its lowermost position, as shown in fulllines in Figs. l and 3, the same is positively locked against upwardswinging movement through the latch plates it-38 by the outwardly curvedlower edges 56-56 of said plates engaging over the pins tlf-3l of thebail member 2l'. Compensation for slight irregularities or variations inthe height of the rloor on which the foot 39 of the bail member 2l restsis provided by permitting the bail member to be locked in variousslightly raised positions above the full line position reerred to. Thisis accomplished by means of the latch plates {iii-38, which have thecurved edge faces -l thereof of decreasing radius from front to rear,thereby permitting the bail member 2l to be locked in any one of saidslightly raised positions when engaged with a floor level which isslightly higher than that shown in Fig. l, the latch plates (iii-33being stopped by engagement with the pins alb-3l in in a position inadvance oi that shown in Fig. l. The llimit of said slight upwarddisplacement of the bail member 2l is indicated in Fig. l andcorresponds with the dotted line position designated by C. This limit isreached when the extreme inner ends of the edge faces SES-5ta oi thelatch plates 33--38 are engaged over the pins Sli-3l. When the bailmember 2li assumes a position above the dotted line position C in Fig.the pins :il-3l thereof are disposed in the path of swinging movement ofthe plates 33H33 and locksaid plates against movement in a clockwisedirection by engagement with the inwardly curved edge faces 5'5-57thereof. This last named position of the bail member 2l corresponds tothe dotted line position D shown in Figs. l and 3. The position of thelatch `plate 38, underv these conditions, is shown in dotted lines inFig. 3. When thus locked, the arms dilt8 or the latch plates 38-33 aredisposed in the path of downward movement of the lower ends of the links22-22 of the ironer unit supporting structure and prevent downward moveyment of said links, thus locking the Vironer unit in folded positionwithin the cabinet. From the foregoing it will be evident that when thebail member 21V is in the dotted line position indicated by D the ironerunit B cannot be Withdrawn from the cabinet.

Assuming that the ironer unit B and the bail member 21 are folded inenclosed position Within the cabinet A, as shown in Fig. 2, thefollowing procedure is followed in making the; ironer unit ready foruse: The attendant, after having opened the door of the cabinet, rstswings the bail member 21 to its lowered position in engagement with thefloor, thereby bringing the stop pins 31-31 of said bail member 21 in aposition to clear the latch plates 35-38 below the same, thus freeingsaid plates to be swung in a clockwise direction. The ironer unit isthen swung outwardly to the position shown in Fig. 1 by pullingoutwardly on the lower end thereof. Under these conditions, the ironerunit is free to be withdrawn from the cabinet as the latch plates Sil-3?I do not obstruct the downward movement of the outer ends of the links22-22, the latch plates being swung in a clockwise direction by thepressure of the links 22-22 on the arms It- 4S of said plates and thetension of the springs i5-45, the rockers 139-49 and the connectinglinks Eli-5l] being freed to swing outwardly as the baseboard I3 of theironer unit B moves outwardly, thus permitting movement of the latchplates 3S--38- The latch plates will thus be swung over the pins 31-31and engage therewith to lock the bail member 21 in its lowered position,which lowered position may be the full line position shown in Figs. 1and 3 or any other position between said full line position and theposition indicated by C in Fig. 1.

In the event that the bail member 21 has not been swung downwardly to anextent to engage the floor and firmly brace and support the cabinet, buthas been swung to a position short of that indicated by C, as forexample the position indicated by D in Figs. 1 and 3, the ironer unit islooked effectively against withdrawal from the cabinet by the latchplates 38-38, the arms 53-48 of which cooperate with the lower ends ofthe links 22-22 of the ironer unit supporting structure.

As hereinbefore pointed out, when the bail member 21 occupies theposition D or any position above the same, the pins 31-31 of the bailmember 21 will be in the path of swinging movement of the latch plates38--38 and lock the same against rotation in a clockwise direction,thereby locking the links 22-22 against downward movement. A safetydevice is thus provided to protect the attendant from possible injury bypreventing withdrawal of the ironer unit from the cabinet when thecabinet is not properly braced against tilting by the extensible bailmember 21.

When the ironer unit is swung back into the cabinet to enclose the sametherein, the baseboard I3 thereof engages the rockers iQ- 49, returningthe same to the position shown in Fig. 2. This movement of the rockers49-49 is communicated through the connecting links'ED-E to the latchplates Sil-38' to restore the latter to the position shown in Fig. 2,swingingl the same clear of the pins 31-31 of the bail member 21, thusunlocking the bail member. The bail member 21 may then be swung upwardto the enclosed position within the cabinet shown in Fig. 2.
